I To all whom it may concern: i

Be it known that l, OLE C. AnnAnAMsoN, a citizen of the United ,States, residing at Minneapolis, in the v county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Railway-Spikes; and l do hereby declare the following to -for coperation therewith to prevent withdrawing of j the spikes from the ties, and has for its object to imtie plates.

prove the same in the several particulars hereinafter noted. v

To the above'ends the invention consists of the novel devices and combinations ofy devices hereinafter de scribed and defined in the claims. In the accompanying drawings which illustrate the invention`.iike characters indicate like parts throughout the severalviews, v Referring to the drawings, Figure 1 is a plan yiew, showing a portion of the rail and a portion of the tie, secured together in accordance with myinvention. Fig. 2 is a vertical section taken on the line x2 .t2 of Fig. 1; and Fig. 3 is aplan view .showing one ofthe so-called The numeral 1 indicates a. tie, and the numeral 2 a railA of ordinary construction. The numeral 3 indicates a tie plate, so-called, which is placed between the tie and the foot iiange of the rail. This tie plate is provided near one end with a spike passage 4, and near its other end with an angular or L-shaped spike passage 5.

The spikes G are provided with the usual heads, but some 'little distance below their heads they are -provided with outwardly projecting lock shoulders 7, the important function of vwhich will presently appear. Preferably also, the spikes are provided at 'their extreme lower ends with small projecting pin portions 8 which are adapted to be driven into thel tie by a very light blow and to hold the spike in an upright position for driving into the tie. The spike passage 4, in a direction longitudinally of the tie plate 3, and transversely of the rail, is of such length that the spike body and lock lug-7 may be freely passed therethrough. The

longitudinally extended portion of the L-shaped spike passage 5 isalso oi the same length, bri-t the laterally I projecting portion fuoi said Vpassage 5 is' only of such width as to pass or receive thebodyof the spike. The

i exact relation of the said spike. passages with respect to each other and in respect to the spikes and the rail, will be more fully understood by description of the manner of applying the spikcsand plate, and of removing the same. l The spike at the left with. respect to Figs. l and 2 must first be driven, and to permit this the tie plate 3 is forced toward the loitso that the inner extremity of its spike passage 4 alines approximately with the outer edge'of the left hund foot flange 'of the rail. Then, when the leit hand spike has been driven to position with its lock lug 7 below the plane of the tie plate 3, the said tie plate is driven toward the right as iar as-it will go, thereby carrying a portion oi the left'hand end of said tie plate directly over the lock lug 7 of the said left hand spike. This movement oi the tie plate brings the inner extremity of the L-shaped spike passage 5 approximately in line with the outer edge of the righthand foot `flange ofv the rail, and the said tie plate should then be positioned approximately as shown by dotted lines in Fig. 3. The right hand spike 6 is then driven to position so :is to carry its vlock lug 7 below the plane of the tie plate 3. Then, the

hand spike vinto the position shown by full lines in I Figs. 1 and 43, thereby carrying a portion of the right hand end of the tie plate over the lock shoulder of the right hand spike.

When the parts are positioned just stated,r it is evident that the spikes are locked into the tie by engagement oi their lock shoulders 7 with the tie plate.

Otherwise stated, it is impossible thon to withdraw either of the spikes from the tie. Any slight tendency that there may be for the spikes to work upward out of the tiewill be offset by-the downward pressurepro thermore, the tie plate ties the spikes 6 together. in v such manner that they can not spread or separate from each other in the tie. Hence, lateral pressures on the rail in either direction will be simultaneously resisted by the spikes en both sides oi the rail.`

If desired, of course, a small spike or nail maybe driven into the tie to positively hold the tie plate 3 in its position shown by full lines in Figs. l and 3., v

' I o remove thespikes 4it will be necessary first to remove the tie plate from the full line position, Figs. 1

and 3,'intothe dotted line position, Fig. 3, and then to withdraw the right hand spike. Then, to drive the tie plate toward the leit as iar'as it will go and then 'withdraw the left hand spike.

The device described, while extremely simple and of small cost, is highly eilicient for the'purposes had in view. v

What l claim is:

i. The combination with u ruil und a tie, of u tie plate interposed between' the same undpi'uvided with spike paissnges, of spikes having projecting lock lugs adapted to be .passed through perforations in4 suld tie platte to' a point below the plane of the tie plate, und which tie plate is adapted to he slid to move portions thereof over the lock lugs oi.' sold spikes und thereby hold thejuid spikes driven Il interposed between said rzli and tie, said tie plate vhav-y` ingwnear one end a spike passage 4, and having near its other end :in approximately L-shaped spike passage 5 5,

` of spikes 6 having outwardly projectingr lock lugs 7, adapted to be passed through the perfor-ations of said tie plate, nnd which tie. plate is adapted by endwise und pivotal movement to be somovel that portions thereof wii-o'v'erlie the lock lugs of said spikes-and thereby hold-the spikes driven 1n the tie, substnntallyns describech 8.
